As stated above, e-mail cannot be used to perform procedural acts (except, under certain conditions, during oral proceedings or interviews held as a video-conference; see C-VII, 2.6, and E-II, 11.3.2). If, e.g. shortly before oral proceedings, the applicant would like to submit new requests and/or amended documents, this should be done by fax, since only this ensures that the filed documents are given a valid date of receipt and form part of the file. Experience has shown that faxes are normally visible in the electronic file on the same day. As stated in C-VII, 2.6.1(iii) above, an informal copy, in addition to the fax, can be sent to the examiner for the convenience of the Division if this is felt necessary due to the short time frame.
